Efficient Large Ratio Compact Planetary Gear System

Efficient Large Ratio Compact Planetary Gear System

As a key component of the planetary transmission system, the planetary gear exhibits unique transmission advantages through the coordinated meshing of the sun gear, planetary gears, and internal gear ring. Its core feature is a large transmission ratio. By utilizing the superposition effect of multi-stage gear meshing, it can achieve single-stage large transmission ratio output, with a transmission ratio range of 3-10, meeting high deceleration or speed increase requirements, reducing the number of transmission stages while improving system integration. Secondly, the structure is extremely compact. The planetary gears are distributed circumferentially around the sun gear, with a short power transmission path and symmetrical layout. Under the same transmission requirements, the volume is 30%-40% smaller than that of traditional fixed-axis gear transmission, facilitating lightweight equipment design. In addition, the load-bearing capacity is outstanding. Multiple planetary gears partic…
